ABSTRACT:
An electrical drive system for angular positioning of one or several rotating and/or tilting machine components and equipment components, particularly of printing machines, including at least one electric motor having a rotor designed for rigid and direct coupling to the component, further including by one or several angle encoders for registering the angular motion of the rotor of the electric motor and/or the component, a signal processing module which receives the actual angle position signals from the angle encoder or encoders and which also receives the setpoint data for comparison with the actual data, and a power amplifier controlled by the signal processor and used for driving the electric motor.
